I'm a first year newbeek. I installed my package of Italian bees on April 10th, so they've been buzzing for 2 weeks now. Their house and all of the equipment is new and I am feeding them a 1:1 sugar syrup. From the best I can tell (and that's not saying much) I haven't seen any...
I have a sour smell in one of my hives. It's not intense but it is distinct. It smells like sour milk or compost. It's not wreaking. I have to get within 2 feet of the hive before I can smell it.
What is this? Any ideas?
